Description

TECHNICAL FIELD

[0001] The application relates to a glass heating die casting method and belongs to the die casting equipment field. BACKGROUND

[0002] A glass rod is heated and then pressed and cast through a die to obtain a glass bead blank, and the die casting machine on the market has not been updated for a long time. The main reason is that the early die casting machine has a simple structure and low equipment cost. In order to increase production capacity, a large number of equipment are laid out. Considering the cost of updating the equipment, most manufacturers still use the early die casting equipment in the industry. Due to the design defects and lack of automation, the die casting machine only uses one set of heating device and die casting mold. After the glass rod is pressed and cast once, it is almost completely cooled before being heated and pressed and cast again. The glass rod needs to consume energy during the heating process. This way of heating again from low temperature greatly causes energy waste. In addition, the rising energy prices lead to high product costs and no competitive advantage for enterprises. SUMMARY
